What is recorded here?
Replaced encoder self-attention with real-valued outputs of Fourier transforms over sequence and hidden dimensions, retaining feed-forward blocks and studying speed–accuracy tradeoffs.
Source-linked catalogue note. A detailed explanatory guide has not yet been prepared for this entry.
Scientific scope
Fourier mixing is not an approximation that preserves each attention matrix or output. FFT and dense-DFT implementations have different complexity and device tradeoffs. Reported speedups use particular encoder tasks and hardware and do not establish drop-in causal decoding equivalence.

FNet: fixed Fourier mixing in language encoders
